Abstract

A constriction part of a container with a squeeze nozzle and a lever is equipped with a nozzle having rubber elasticity and a lever that indirectly pinches the nozzle. The nozzle has a storage part, a base part, and a valve. The storage part is provided in the constriction part and when the nozzle is pinched by the lever and flattened, continuity with the main body is interrupted by the inner walls of the part that is continuous with the interior of the main body being tight against one another. During use the valve is opened when the internal pressure of the storage part exceeds a specific pressure, and a liquid in the storage part is ejected. During use the constriction part of the nozzle expands by being pinched by the lever until the internal pressure of the storage part reaches a specific pressure. When the valve releases, the constriction part contracts due to the rubber elasticity, so liquid in the storage part is ejected.

　薬液を滴下させる方式の点眼容器は、特許文献１～５に開示されている。これらの点眼容器は、ノズルが下に向くように逆さまにされて用いられる。利用者が容器を押圧すると、薬液はノズルから流出し滴下される。したがって、利用者は、点眼するために滴下される薬液を仰ぎ見ることとなる。 Patent Documents 1 to 5 disclose eye drop containers of a type in which a chemical solution is dropped. These eye drops are used upside down so that the nozzle faces downward. When the user presses the container, the chemical solution flows out from the nozzle and is dropped. Therefore, the user looks up at the drug solution dripped for instilling.
　特許文献１～５に示された点眼容器では、真上を見た状態でうまく眼球に薬液を滴下させるために、慣れが必要である。体が硬いなどの理由から上を向くことが困難な場合、薬液をうまく滴下できない。また、上を向くと反射的に口が開いてしまうため、点眼しているときの姿を他人に見られると恥ずかしい。そこで、上を向くことなく目に薬液を供給するための目薬容器が特許文献６～８に開示されている。 In the eye drops containers shown in Patent Documents 1 to 5, it is necessary to get used to dripping the drug solution onto the eyeballs in a state where they are seen directly above. If it is difficult to face up because the body is hard, the drug solution cannot be dripped well. Also, if you look up, your mouth will open up reflectively, so it would be embarrassing if you can see the appearance of your eyes. Therefore, Patent Documents 6 to 8 disclose eye drops containers for supplying a chemical solution to the eyes without facing upward.

　特許文献６に記載されたスプレー式点眼器は、薬液を噴出させるために指でボタンを押圧する際に手が動いてしまい、目にうまく噴霧することができない場合がある。特許文献７および特許文献８に記載された目薬容器は、ノズルが常に開口しているので、容器を瞬時に指で押圧しないと、薬液を噴出する内圧が不足し、ノズルから薬液が垂れる。 The spray-type eyedropper described in Patent Document 6 may not be able to be sprayed well on the eyes because the hand moves when the button is pressed with a finger to eject the liquid medicine. In the eye drop containers described in Patent Document 7 and Patent Document 8, since the nozzle is always open, if the container is not instantaneously pressed with a finger, the internal pressure for ejecting the chemical liquid is insufficient, and the chemical liquid drips from the nozzle.
　また、特許文献６および特許文献８に記載された目薬容器は、いずれも複雑な機構を要しており、衛生面から使い捨てにされる容器として不経済である。　 In addition, the eye drop containers described in Patent Document 6 and Patent Document 8 both require a complicated mechanism and are uneconomical as disposable containers from the viewpoint of hygiene. *
　そこで、本発明は、容器の姿勢によらずに内部の液体をノズルから噴出させることができるとともに、構造が単純で安価に製造できる搾出ノズルおよびレバー付の容器を提供する。 Therefore, the present invention provides a container with a squeezing nozzle and a lever that can eject an internal liquid from a nozzle regardless of the posture of the container and can be manufactured at a low cost with a simple structure.
　本発明に係る搾出ノズルおよびレバー付の容器は、開口部を有して液体を内部に溜める本体と、開口部に装着されて先端側の狭窄部にゴム弾性を有したノズルと、狭窄部を間接的に摘むために狭窄部に隣接して配置されるレバーと、ノズルを覆って取り外し可能に装着される蓋とを備える。 A squeezing nozzle and a container with a lever according to the present invention include a main body that has an opening and stores liquid therein, a nozzle that is attached to the opening and has rubber elasticity at the narrowed portion on the distal end side, and a narrowed portion A lever disposed adjacent to the constriction and a lid that is detachably mounted over the nozzle.
　ノズルは、貯留部と台部と弁とを有する。貯留部は、狭窄部の中に設けられ、レバーによって狭窄部が摘まれていない自由状態で本体の内部と連通している。貯留部は、レバーによって狭窄部が摘まれ扁平された被操作状態で、本体の内部との連通部で対向する内壁どうしを密着させることによって本体の内部との連通が遮断される。台部は、開口部に嵌合し、開口部から貯留部へ通じる液体供給路を有する。弁は、被操作状態で貯留部の内圧が一定の圧力を超えた場合に開かれて貯留部内の液体を噴出させる。ノズルの狭窄部は、被操作状態で貯留部の内圧が一定の圧力に至るまで、レバーで摘まれることによって膨張する。 The nozzle has a storage part, a base part, and a valve. The storage part is provided in the stenosis part and communicates with the inside of the main body in a free state where the stenosis part is not picked up by the lever. The reservoir is in an operated state in which the constriction is picked and flattened by a lever, and communication between the inside of the main body is blocked by bringing the opposing inner walls into close contact with each other at the communication portion with the inside of the main body. The base has a liquid supply path that fits into the opening and communicates from the opening to the storage. The valve is opened when the internal pressure of the reservoir exceeds a certain pressure in the operated state, and ejects the liquid in the reservoir. The narrowed portion of the nozzle expands by being picked by the lever until the internal pressure of the reservoir reaches a certain pressure in the operated state.
　レバーは、操作されることによって、第１姿勢を経た後、第２姿勢へ変位する。第１姿勢においてレバーは、狭窄部を扁平し、本体の内部との連通部の対向する内壁どうしを密着させることで貯留部を本体から遮断する。第２姿勢においてレバーは、貯留部と本体とを遮断した状態を維持しつつ、貯留部を弁に向かって絞り上げるように狭窄部を扁平させる。 When the lever is operated, the lever moves to the second posture after passing through the first posture. In the first posture, the lever flattens the constricted portion, and closes the storage portion from the main body by bringing the opposing inner walls of the communicating portion with the inside of the main body into close contact with each other. In the second posture, the lever flattens the constriction portion so as to squeeze the storage portion toward the valve while maintaining the state where the storage portion and the main body are shut off.
　上記構成を備える搾出ノズルおよびレバー付の容器において、レバーは、本体側に固定された基部と、基部から延びる起立部と、ノズルの先端側でノズルから離れる方向へ折り返された操作部と、操作部から狭窄部に向かって起立部を回り込んで延び狭窄部に対面する当接部と、を有するとよい。この場合、レバーは、狭窄部を挟んで対称の位置に一対に設けられるとよい。 In the squeezing nozzle and lever-equipped container having the above-described configuration, the lever includes a base portion fixed to the main body side, an upright portion extending from the base portion, and an operation portion folded back in a direction away from the nozzle on the tip end side of the nozzle, It is preferable to have an abutting portion that extends from the operation portion toward the stenosis portion, extends around the standing portion, and faces the stenosis portion. In this case, the levers may be provided in a pair at symmetrical positions with the narrow portion interposed therebetween.
　また、上記構成を備える搾出ノズルおよびレバー付の容器において、ノズルは、レバーによって狭窄部が扁平された場合に液体供給路と貯留部との間を閉塞する凸部を有するとよい。 In the squeezing nozzle and lever-equipped container having the above-described configuration, the nozzle may have a convex portion that closes between the liquid supply path and the storage portion when the narrowed portion is flattened by the lever.
　また、上記構成を備える搾出ノズルおよびレバー付の容器において、弁は、貯留部の内圧が一定の圧力以下で気密に密閉されており一定の圧力を超えた場合に拡開されて貯留部内の液体を噴出させるピンホールであるとよい。 Further, in the squeezing nozzle and lever-equipped container having the above-described configuration, the valve is hermetically sealed when the internal pressure of the reservoir is below a certain pressure, and is expanded when the pressure exceeds a certain pressure. It may be a pinhole that ejects liquid.
　弁の他の具体的な形状は、ピンホールである以外に、液体が通る噴出方向に沿って幅を有しており貯留部の内圧が一定圧力以下で気密に密着し一定圧力を超えると開放されるスリットまたはこのスリットが十字に交差されたものであってもよい。 Other specific shapes of the valve, other than a pinhole, have a width along the jet direction through which the liquid passes, and when the internal pressure of the reservoir is tightly closed below a certain pressure, it opens when it exceeds a certain pressure Or a slit crossed in a cross shape.
　また、蓋は、装着された状態でレバーが第２姿勢に変位することを阻止する係止部を有していてもよい。 Further, the lid may have a locking portion that prevents the lever from being displaced to the second posture in the mounted state.
　本願において「噴出」とは、液体がノズルの先端から飛沫となって飛翔することを意味する。このときの飛沫は、液体が自重によって滴下される一滴の液量よりも少量の液滴である。 In the present application, “spout” means that the liquid splashes from the tip of the nozzle. The droplets at this time are droplets that are smaller than the amount of one droplet in which the liquid is dropped by its own weight.
　上記構造を備える本発明に係る搾出ノズルおよびレバー付の容器によれば、重力に逆らって本体内部の液体をノズルから噴出させることができる。この場合、液体は飛沫となってノズルから打ち出される。 According to the squeezing nozzle and the lever-equipped container according to the present invention having the above structure, the liquid inside the main body can be ejected from the nozzle against gravity. In this case, the liquid is splashed and ejected from the nozzle.
　本発明に係る搾出ノズルおよびレバー付の容器を目薬容器として使用する場合、利用者は、上を仰ぎ見ることなく、正面または下を向いた姿勢でも薬液を目に供給することができる。この容器は、重力に影響されることなく内容液をノズルから噴出させることができる。したがって、上を向くことが困難な者でも容易に目薬をさすことができるだけでなく、無重力空間においても目薬容器として利用できる。 When using the container with the squeezing nozzle and lever according to the present invention as an eye drop container, the user can supply the liquid medicine to the eyes even in a posture facing front or down without looking up. This container can eject the liquid from the nozzle without being affected by gravity. Therefore, even a person who has difficulty in facing up can easily apply eye drops, and can also be used as an eye drop container in a weightless space.
　また、本発明の搾出ノズルおよびレバー付の容器は、構造が単純であり安価に製造できるため、衛生上使い捨てにされる目薬容器として適している。 Further, the container with the squeezing nozzle and lever of the present invention is suitable as an eye drop container that is sanitary disposable because it has a simple structure and can be manufactured at low cost.

　本発明に係る第１の実施形態の容器１について、目薬容器として利用される場合を例に、図１から図７を参照して説明する。図１に示す容器１は、搾出ノズルおよびレバー付の容器であって、本体２とノズル３とレバー４と蓋５とを備える。本体２は、開口部２１を有し、内部に薬液である液体Ｌを溜める。本体２は、内部の液体Ｌによって劣化しないとともに内容物の液体Ｌに溶出してこの液体Ｌの純度を損なわない材質、例えば、ガラス、ポリプロピレンなどの合成樹脂、アルミニウムなどの合金で形成されることが望ましい。 The container 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 7 by taking as an example a case where it is used as an eye drop container. A container 1 illustrated in FIG. 1 is a container with an extraction nozzle and a lever, and includes a main body 2, a nozzle 3, a lever 4, and a lid 5. The main body 2 has an opening 21 and stores a liquid L which is a chemical solution inside. The main body 2 is formed of a material that does not deteriorate due to the liquid L inside and does not deteriorate the purity of the liquid L by elution, such as a synthetic resin such as glass or polypropylene, or an alloy such as aluminum. Is desirable.
　図２に示すように、ノズル３は、開口部２１に装着され、先端側の狭窄部３２にゴム弾性を有している。ノズル３は、本体２の中に液体Ｌを入れた後、開口部２１から容易に脱落しない方法で固定されている。この実施形態では、ノズル３は、本体２の開口部２１に圧入されて嵌合している。圧入したのち接着してもよいし、本体２とノズル３とが合成樹脂どうしであれば、レーザーや超音波によって互いに融着させてもよい。 As shown in FIG. 2, the nozzle 3 is attached to the opening 21 and has a rubber elasticity in the narrowed portion 32 on the distal end side. The nozzle 3 is fixed by a method that does not easily drop out from the opening 21 after the liquid L is put into the main body 2. In this embodiment, the nozzle 3 is press-fitted into and fitted into the opening 21 of the main body 2. After press-fitting, bonding may be performed, or if the main body 2 and the nozzle 3 are made of synthetic resin, they may be fused together by laser or ultrasonic waves.
　レバー４は、狭窄部３２を間接的に摘めるようにノズル３の狭窄部３２に隣接している。蓋５は、図１に示すように、ノズル３を覆う形状を有し、取り外し可能に装着されている。蓋５は、この容器１を携行する際に容易に脱落せずノズル３を保護できればよい。したがって、蓋５は、本体２やノズル３あるいはレバー４に外嵌する形状であってもよい。 The lever 4 is adjacent to the narrowed portion 32 of the nozzle 3 so that the narrowed portion 32 can be indirectly picked. As shown in FIG. 1, the lid 5 has a shape covering the nozzle 3 and is detachably mounted. The lid 5 only needs to be able to protect the nozzle 3 without easily falling off when carrying the container 1. Therefore, the lid 5 may have a shape that fits around the main body 2, the nozzle 3, or the lever 4.
　ノズル３は、図２に示すように、台部３１と狭窄部３２とで構成され、貯留部３３と液体供給路３４と弁３５と凸部３６とが形成されている。台部３１は、開口部２１に嵌合し、開口部２１から貯留部３３へ通じる液体供給路３４を有する。本体２と反対側の台部３１には、狭窄部３２が嵌着されている。狭窄部３２は、繰り返し扁平された場合にも復元性に優れた部材、シリコーンゴムやウレタンエラストマなどによって形成されている。狭窄部３２は、台部３１から取れないように嵌着されるか、段差を設けて嵌合される。狭窄部３２は、台部３１に対して嵌着されるだけでなく、液密となるように、接着剤で固定されるかレーザーや超音波で融着されるとよい。また、台部３１を硬い材質、狭窄部３２を柔らかい材質で、一体に射出整形してもよい。 As shown in FIG. 2, the nozzle 3 includes a base portion 31 and a constricted portion 32, and a storage portion 33, a liquid supply path 34, a valve 35, and a convex portion 36 are formed. The base 31 has a liquid supply path 34 that fits into the opening 21 and communicates from the opening 21 to the reservoir 33. A narrowed portion 32 is fitted to the base portion 31 on the side opposite to the main body 2. The narrowed portion 32 is formed of a member having excellent resilience even when repeatedly flattened, such as silicone rubber or urethane elastomer. The narrowed portion 32 is fitted so as not to be removed from the base portion 31 or is fitted with a step. The narrowed portion 32 is not only fitted to the base portion 31, but is preferably fixed with an adhesive or fused with a laser or an ultrasonic wave so as to be liquid-tight. Alternatively, the base 31 may be injection molded integrally with a hard material and the narrowed portion 32 may be made of a soft material.
　液体供給路３４の開口部２１側には、本体２の底に達する長さの導管３７が装着されている。液体供給路３４は、貯留部に入った液体Ｌをその液体Ｌの表面張力によって、そのまま貯留部３３に残留させる程度に貯留部３３よりも細く形成される。また、台部３１は、本体２内部の圧力を大気圧にするための連通孔３８を有している。連通孔３８は、気体を通し液体Ｌを通さない半透膜で覆われることも好ましい。 A conduit 37 having a length reaching the bottom of the main body 2 is attached to the opening 21 side of the liquid supply path 34. The liquid supply path 34 is formed to be narrower than the reservoir 33 to such an extent that the liquid L that has entered the reservoir is left in the reservoir 33 as it is due to the surface tension of the liquid L. Further, the base portion 31 has a communication hole 38 for setting the pressure inside the main body 2 to atmospheric pressure. It is also preferable that the communication hole 38 is covered with a semipermeable membrane that allows gas to pass and does not allow the liquid L to pass.
　貯留部３３は、狭窄部３２の中に形成されている。貯留部３３は、自由状態で本体２の内部と連通しており、被操作状態で本体２の内部との連通が遮断される。自由状態とは、レバー４によって狭窄部３２が摘まれていない状態である。被操作状態とは、レバー４によって狭窄部３２が摘まれ扁平された状態である。 The reservoir 33 is formed in the constriction 32. The reservoir 33 communicates with the inside of the main body 2 in a free state, and the communication with the inside of the main body 2 is blocked in the operated state. The free state is a state in which the narrowed portion 32 is not picked by the lever 4. The operated state is a state in which the narrowed portion 32 is picked and flattened by the lever 4.
　弁３５は、ピンホールであって、台部３１と反対側の狭窄部３２の先端に設けられている。弁３５は、貯留部３３の内圧が一定の圧力以下で気密に窄まって密閉されている。狭窄部３２が被操作状態となり貯留部３３の内圧が一定の圧力を超えた場合、弁３５は弾性変形によって拡開され、貯留部３３内の液体Ｌを噴出させる。 The valve 35 is a pinhole and is provided at the tip of the narrowed portion 32 on the side opposite to the base portion 31. The valve 35 is hermetically sealed when the internal pressure of the reservoir 33 is equal to or lower than a certain pressure. When the constricted portion 32 becomes an operated state and the internal pressure of the storage portion 33 exceeds a certain pressure, the valve 35 is expanded by elastic deformation, and the liquid L in the storage portion 33 is ejected.
　狭窄部３２は、被操作状態で貯留部３３の内圧が開弁される一定の圧力に達するまでレバーで摘まれ扁平すると、レバー４に接していない部分が膨張する。凸部３６が閉塞された後にレバー４で加えられた押圧力は、狭窄部３２が膨張されたことで生じるゴム弾性の収縮力として蓄えられる。貯留部３３の内圧が上昇し弁３５が開放されると、引き伸ばされていた狭窄部３２は、ゴム弾性によって収縮する。この結果、貯留部３３内の液体Ｌは、弁３５を通って勢いよく噴出される。 When the stenosis part 32 is picked and flattened by the lever until the internal pressure of the storage part 33 reaches a certain pressure at which the internal pressure of the storage part 33 is opened in the operated state, the part not in contact with the lever 4 expands. The pressing force applied by the lever 4 after the projection 36 is closed is stored as a rubber elastic contraction force generated by the expansion of the narrowed portion 32. When the internal pressure of the reservoir 33 rises and the valve 35 is opened, the stretched constriction 32 contracts due to rubber elasticity. As a result, the liquid L in the reservoir 33 is ejected vigorously through the valve 35.
　凸部３６は、貯留部３３と液体供給路３４との間に形成されている。この凸部３６は、図５および図６に示すように、狭窄部３２がレバー４によって摘まれて扁平させられた場合に、貯留部３３と液体供給路３４との間を閉塞し、流れを遮断する。凸部３６が設けられていることによって、小さな力でも貯留部３３と液体供給路３４との間を閉塞することができる。なお、レバー４によって狭窄部３２を扁平したときに貯留部３３と液体供給路３４との間の部分の内壁どうしが密着することで、貯留部３３と液体供給路３４との間が遮断されれば、凸部３６は必須ではない。 The convex portion 36 is formed between the storage portion 33 and the liquid supply path 34. As shown in FIGS. 5 and 6, when the narrowed portion 32 is picked and flattened by the lever 4, the convex portion 36 closes the space between the storage portion 33 and the liquid supply path 34, thereby preventing the flow. Cut off. By providing the convex portion 36, the space between the storage portion 33 and the liquid supply path 34 can be closed even with a small force. When the constricted portion 32 is flattened by the lever 4, the inner wall of the portion between the storage portion 33 and the liquid supply path 34 is in close contact with each other, so that the storage portion 33 and the liquid supply path 34 are blocked. For example, the convex part 36 is not essential.
　レバー４は、図１～図３に示すように、ノズル３を挟んで対称となる位置に一対に配置されている。レバー４は、基部４１と起立部４２と操作部４３と当接部４４とで構成されている。本実施形態において基部４１は、ノズル３の台部３１を囲う環状に一続きに形成されている。基部４１は、内側に雌螺子４５を有し、本体２の開口部２１の外周に形成された雄螺子２２に螺合されることによって本体２に固定されている。 As shown in FIGS. 1 to 3, the levers 4 are arranged in a pair at symmetrical positions with the nozzle 3 in between. The lever 4 includes a base portion 41, an upright portion 42, an operation portion 43, and a contact portion 44. In the present embodiment, the base portion 41 is formed continuously in an annular shape surrounding the base portion 31 of the nozzle 3. The base 41 has a female screw 45 on the inner side, and is fixed to the main body 2 by being screwed into a male screw 22 formed on the outer periphery of the opening 21 of the main body 2.
　起立部４２は、狭窄部３２と平行に弁３５に向かって延びている。操作部４３は、ノズル３の先端側で起立部４２とつながっており、狭窄部３２から離れる方向へ折り返されている。操作部４３の表面には、滑り止めの凸条が多数形成されている。当接部４４は、操作部４３の両側縁から狭窄部３２に向かって起立部４２を回り込んで延び、狭窄部３２に対面している。当接部４４は、起立部４２および操作部４３と別体に製造され、図４に示すように、接着または融着される。なお、レバー４は、金型を工夫することで、一体に射出整形することも可能である。 The standing portion 42 extends toward the valve 35 in parallel with the narrowed portion 32. The operation portion 43 is connected to the standing portion 42 on the tip end side of the nozzle 3 and is folded back in a direction away from the narrowed portion 32. A number of anti-slip ridges are formed on the surface of the operation unit 43. The contact portion 44 extends from both side edges of the operation portion 43 around the upright portion 42 toward the narrowed portion 32, and faces the narrowed portion 32. The contact part 44 is manufactured separately from the upright part 42 and the operation part 43, and is bonded or fused as shown in FIG. The lever 4 can be integrally injection-shaped by devising a mold.
　当接部４４は、貯留部３３の弁３５側より手前の部分から凸部３６までの範囲にわたって設けられている。図２に示すように、凸部３６側の当接部４４は、弁３５側の部分よりも操作部４３から離れている。これにより、レバー４を操作した場合、凸部３６側の当接部４４が先に狭窄部３２に接触する。 The contact portion 44 is provided over a range from a portion in front of the valve portion 35 side of the storage portion 33 to the convex portion 36. As shown in FIG. 2, the contact portion 44 on the convex portion 36 side is farther from the operation portion 43 than the portion on the valve 35 side. Thereby, when the lever 4 is operated, the contact portion 44 on the convex portion 36 side comes into contact with the narrowed portion 32 first.
　上述の構造を有したレバー４は、利用者によって指で狭窄部３２を間接的に摘むように操作される。レバー４は、操作されることによって、図５に示す第１姿勢Ｐ１を経た後、図６に示す第２姿勢Ｐ２へ変位する。第１姿勢Ｐ１においてレバー４は、狭窄部３２を扁平して貯留部３３を本体２から遮断する。第２姿勢Ｐ２においてレバー４は、貯留部３３と本体２とを遮断した状態を維持しつつ、貯留部３３を弁３５に向かって絞り上げるように狭窄部３２を扁平させる。 The lever 4 having the above-described structure is operated by the user so as to indirectly pick the narrowed portion 32 with a finger. The lever 4 is operated to move to the second posture P2 shown in FIG. 6 after passing through the first posture P1 shown in FIG. In the first posture P <b> 1, the lever 4 flattens the narrowed portion 32 and blocks the storage portion 33 from the main body 2. In the second posture P2, the lever 4 flattens the narrowed portion 32 so as to squeeze the storage portion 33 toward the valve 35 while maintaining the state where the storage portion 33 and the main body 2 are shut off.
　つまり、レバー４は操作されると、起立部４２と操作部４３との連結部を中心に、操作部４３および当接部４４が狭窄部に向かって回動し、第１姿勢Ｐ１となる。凸部３６があたっているので、さらにレバー４に力が加えられると、基部４１側を固定端とした梁のように、レバー４の起立部４２は撓む。そして、当接部４４が貯留部３３を弁３５に向かって絞り上げるように狭窄部３２を扁平し、レバー４は第２姿勢Ｐ２となる。 That is, when the lever 4 is operated, the operation portion 43 and the contact portion 44 are rotated toward the constriction portion around the connecting portion between the standing portion 42 and the operation portion 43, and the first posture P1 is obtained. Since the convex portion 36 is hit, when the force is further applied to the lever 4, the standing portion 42 of the lever 4 bends like a beam having the base 41 side as a fixed end. And the constriction part 32 is flattened so that the contact part 44 may squeeze the storage part 33 toward the valve 35, and the lever 4 will be in the 2nd attitude | position P2.
　第１姿勢Ｐ１から第２姿勢Ｐ２へレバー４が変位する間、貯留部３３の内圧が一定の圧力を超えるまで弁３５は閉じられている。そのためレバー４によって狭窄部３２に加えられた変形力は、レバー４に接していない狭窄部３２が膨張することで生じる収縮力として狭窄部３２に蓄えられる。 While the lever 4 is displaced from the first posture P1 to the second posture P2, the valve 35 is closed until the internal pressure of the reservoir 33 exceeds a certain pressure. Therefore, the deformation force applied to the narrowed portion 32 by the lever 4 is stored in the narrowed portion 32 as a contracting force generated by the expansion of the narrowed portion 32 not in contact with the lever 4.
　貯留部３３の内圧が弁３５を開放させる一定の圧力を超えると、図６に示すように弁３５が開き、膨張した狭窄部３２のゴム弾性によって蓄積されていた収縮力によって、貯留部３３内の液体Ｌが勢いよく噴出する。液体Ｌは、勢いよく噴出するので、液体Ｌが自重で滴下される一滴よりも少量の飛沫となってノズル３の先端から飛翔する。 When the internal pressure of the storage part 33 exceeds a certain pressure for opening the valve 35, the valve 35 opens as shown in FIG. 6, and the contraction force accumulated by the rubber elasticity of the expanded constriction part 32 causes the inside of the storage part 33 to be opened. Liquid L erupts vigorously. Since the liquid L is ejected vigorously, the liquid L is ejected from the tip of the nozzle 3 in a smaller amount than one droplet dropped by its own weight.
　貯留部３３内の圧力が一定圧力よりも低下すると、弁３５は弾性力によって閉鎖される。貯留部３３に入っていた液体Ｌが噴出されると、狭窄部３２をレバー４で摘んだ第２姿勢Ｐ２のままでも、自然と弁３５は閉じられる。手を緩めてレバー４が戻り、狭窄部３２が自由状態に復元されると、導管３７を通して本体２に入っている液体Ｌが貯留部３３に吸い上げられる。 When the pressure in the reservoir 33 drops below a certain pressure, the valve 35 is closed by elastic force. When the liquid L contained in the storage portion 33 is ejected, the valve 35 is naturally closed even in the second posture P2 where the narrow portion 32 is picked by the lever 4. When the hand 4 is released and the lever 4 returns and the constricted portion 32 is restored to the free state, the liquid L contained in the main body 2 is sucked into the storage portion 33 through the conduit 37.
　蓋５は、切欠き部５１とフック５２とを有している。切欠き部５１は、レバー４に対応して２か所、レバー４と嵌合するように設けられている。フック５２は、２つの切欠き部５１の間に設けられており、レバー４の基部４１に設けられた凹部４６と係合する。レバー４の基部４１を押圧するように蓋５を扁平させると、フック５２が凹部４６から解除される。また、図２に示すように蓋５は、レバー４が第２姿勢Ｐ２にならないように起立部４２の先端側を支持する係止部５３を内側に備えている。 The lid 5 has a notch 51 and a hook 52. The notch 51 is provided at two locations corresponding to the lever 4 so as to be fitted to the lever 4. The hook 52 is provided between the two notches 51 and engages with a recess 46 provided in the base 41 of the lever 4. When the lid 5 is flattened so as to press the base 41 of the lever 4, the hook 52 is released from the recess 46. As shown in FIG. 2, the lid 5 includes a locking portion 53 that supports the distal end side of the standing portion 42 so that the lever 4 does not assume the second posture P2.
　以上のように構成された容器１は、重力に影響されることなく液体Ｌをノズル先端から噴出させることができる。したがって、この容器を使用すれば、利用者は、図７に示すように正面を向いた状態、さらには下を向いた状態でも、薬液を眼にさすことができる。目薬をさすのに上を向く必要がないので、上を向くことが困難な人も容易に目薬をさすことができる。また、愛玩動物に目薬をさすことも容易である。さらに、宇宙空間など無重力環境であっても、目薬をさすことができる。 The container 1 configured as described above can eject the liquid L from the nozzle tip without being affected by gravity. Therefore, if this container is used, the user can touch the liquid medicine in his / her eyes even in a state of facing the front as shown in FIG. Since it is not necessary to face up to apply eye drops, even those who have difficulty in facing up can easily apply eye drops. It is also easy to apply eye drops to pets. Furthermore, eye drops can be applied even in a zero gravity environment such as outer space.
　貯留部３３に入っている液体Ｌは、狭窄部３２のゴム弾性力による収縮力で液体Ｌを噴出される。したがって、貯留部３３の容積は、液体Ｌが自重で滴下される一滴よりも少ない微量であっても、液体Ｌを飛沫化して噴出させることができる。勢いよく液体Ｌが噴出されるので、ノズル３の先端から液体Ｌが垂れることを防止できる。 The liquid L contained in the storage part 33 is ejected by the contraction force due to the rubber elastic force of the constriction part 32. Therefore, even if the volume of the storage part 33 is a trace amount smaller than one drop by which the liquid L is dripped by its own weight, the liquid L can be splashed and ejected. Since the liquid L is ejected vigorously, the liquid L can be prevented from dripping from the tip of the nozzle 3.
　なお、本発明の容器を試作してみたところ、ノズル３から噴出された液体Ｌは、ノズル３から約１５ｃｍ以上直線的に飛翔することが確認された。 In addition, as a result of trial manufacture of the container of the present invention, it was confirmed that the liquid L ejected from the nozzle 3 flies linearly from the nozzle 3 by about 15 cm or more.
　本発明の搾出ノズルおよびレバー付の容器は、目薬容器、香水用容器、液体調味料容器のほか、内部に貯留する液体が滴下される１滴よりも少ない微小量の液体を噴出させたり、重力に抗って微小量の液体を噴出させたりする容器として利用できる。 The squeezing nozzle and the container with a lever of the present invention, in addition to the eye drop container, the container for perfume, and the liquid seasoning container, eject a minute amount of liquid less than one drop into which the liquid stored inside is dripped, It can be used as a container that ejects a small amount of liquid against gravity.
